ResourceChange
import type { ResourceChange } from "https://aws-api.deno.dev/v0.3/services/cloudformation.ts?docs=full";
The ResourceChange
structure describes the resource and the action that CloudFormation will perform on it if you execute this change set.
§Properties
The action that CloudFormation takes on the resource, such as Add
(adds a new resource), Modify
(changes a resource), Remove
(deletes a resource), Import
(imports a resource), or Dynamic
(exact action for the resource cannot be determined).
For the Modify
action, a list of ResourceChangeDetail
structures that describes the changes that CloudFormation will make to the resource.
The resource's logical ID, which is defined in the stack's template.
Contains information about the module from which the resource was created, if the resource was created from a module included in the stack template.
The resource's physical ID (resource name). Resources that you are adding don't have physical IDs because they haven't been created.
For the Modify
action, indicates whether CloudFormation will replace the resource by creating a new one and deleting the old one.
This value depends on the value of the RequiresRecreation
property in the ResourceTargetDefinition
structure.
For example, if the RequiresRecreation
field is Always
and the Evaluation
field is Static
, Replacement
is True
.
If the RequiresRecreation
field is Always
and the Evaluation
field is Dynamic
, Replacement
is Conditionally
.
If you have multiple changes with different RequiresRecreation
values, the Replacement
value depends on the change with the most impact.
A RequiresRecreation
value of Always
has the most impact, followed by Conditionally
, and then Never
.
For the Modify
action, indicates which resource attribute is triggering this update, such as a change in the resource attribute's Metadata
, Properties
, or Tags
.
